A wee bit different than the American white-washing and erasing of history.
The Soviet overlords were despised in Prague! The Czechs are wonderful allies of ours, same as the Poles!
When you erase history, you don’t get it back. It doesn’t matter how great your allies are or how noble their intent. That tactile reminder of history- regardless of the reasons established is lost for reflection and review.
Then your successive generations get to learn bitter lessons all over again.
